Detailed Description

The Set-DPMDatasourceDiskAllocation cmdlet changes disk allocation for protected data. By default, System Center 2012 – Data Protection Manager (DPM) allocates disk space and volumes for the data source. The cmdlet gives you the following options for changing disk allocation:

-- Specify the amount of disk space to allocate to each data source in a protection group.
-- Specify the volumes to use for each data source in a protection group.

Parameters

-AutoGrow<Boolean>

Indicates whether DPM increases the size of the replica or recovery point volume automatically when it runs out of user space.
